Can you loose you data when upgrading from snow leopard to os lion?

Will I loose my data if I upgrade from os leopard to lion?

You can lose your data during any upgrade, in fact you don't even need to be doing anything out of the ordinary for your  hard drive to die. Therefore it is vital that you always have a current backup of your system, preferably a Time Machine backup and a bootble clone made through a program such as Carbon Copy Cloner. This is essential if by chance something does go wrong.
Now I've finished scaring you, I have never had a bad experience updating or upgrading, but as your data is precious you really have to protect it just in case.
Good Luck

  • Time machine can not access time capsule after upgrade from snow leopard to mountain lion

    Two days ago I upgraded my 2009 17" MBP from Snow Leopard to Mountain Lion. That evening my time capsule/time machine combination worked fine and did an incremental backup of about 12 gigabyte. Yesterday - only one day later - the time machine backup did not work anymore.
    It appears that the system can not find the time capsule - even though it shows the remaining free space on the time capsule (so it did find it after all).
    The message is always the same:
    Time Machine can not complete the backup "Time Capsule"
    The image of the backup volume "/Volumes/Data/Pauls MacBookPro.sparsebundle" is not accessable (Error -1).
    I also can not delete the backup image on the time capsule since it is read-only. And I do not want to format the time caspsule yet since my wife's MBAir is also using the same time casule.
    I tried out all kinds of suggestions (hard and soft resetting both the MBP and the TC, entering the password again, setting the TC up again) all to no avail. No backup is possible anymore.

    Sounds like you got this message earlier:
    If so, see #C13 in Time Machine - Troubleshooting.
    Offhand, I don't recall anyone not being able to delete one via the Finder (but most were only backing-up one Mac, so just erased the disk).
    You may have to wait for that message to appear again (24 hours later), or you might try holding Alt/Option with the TM icon in the menubar, and select Verify Backups if it will let you.

  • Upgrade from Snow Leopard to Mountain Lion erase my Windows partition?

    Dear all,
    I know some one might have asked it but I just wanna re-confirm.
    Would the upgrade from Snow Leopard to Mountain Lion erase my Windows partition? I am currently using Bootcamp on my Macbook Pro (Late 2010 Version) and I do not have parallel desktop. I asked the same question when Lion was released, but HK Apple Store said YES and Melbourne Apple Store said no. I am a bit confused now.
    Thank you for answering. Cheers!

    Nothing.
    That said, you should ALWAYS have a backup as anything can happen at anytime.

  • Search in finder doesn't find my files in OS 10.8, upgrade from snow Leopard to Mountain Lion

    after i upgraded from snow leopard to mountain lion . when i try too search files on finder . it does not find any of them although all the files are still there .so i need scroll up and down for few minutes to find my file manually . what could be the problem ?? anyone can help me with this .. thanks in advance

    Hmm... didn't help me. But, I'm glad to know that I can "refresh" the search profiles. That may come in handy in the future.
    I'm having similar problems where I can see a file from within an application, but the file doesn't show up in a Finder search. The file I see in the application also isn't visible in that application's folder (where it's supposed to be stored, in this case).
    The file exists, because I'm able to work on it from within the application. However, it can't be found on the computer by any means I have available. I've spoken with the manufacturer of the software and they told me where to look for the file, but it isn't there (as far as I can see). Of course, they suggest the Finder is "broken" and needs to be fixed. I don't think that's the case. I can easily find other files without difficulty.
    Could what I'm looking for be a "hidden" file?

  • Will upgrading from Snow Leopard to Mountain Lion create problems within Premiere projects?

    I'm looking at the probability of upgrading from Mac OSX 10.6 to 10.8 (Mountain Lion).  I have to if I want to install or upgrade just about anything at this point.
    I was hoping to wait until the latest Premiere project was finished to avoid creating possible discrepancies between how the project plays back before and after the upgrade.  I'll skip the details and just say that it might be best if I do the upgrade now and install a new GPU to help with the massive amounts of rendering/playback needed.  Will upgrading from Snow Leopard to Mountain Lion cause any likely problems?  No other Adobe apps are involved with this project.
    I'm running a Mac Pro 5,1 and Adobe CS6.  I have two separate clone drives of my current boot disk as well as a Time Machine back up.  So I can go back if I really need to.  I'll also make sure the project is saved manually elsewhere.
    Thanks for any input!

Can anyone please help me I really need these programs for my work. Thank you!

    hi tuggerose
    i think it is bad new for you. if it's any consilation i went through the same thing when i loaded mountain lion when it first came out. i think the problem is that mountain lion is a pure 64bit operating system and the software you have is 32bit. earlier os's were able to emulate 32bit but the new system does not. the answer is new software. i did it and it cost me a load of money and much angst so your not alone.

  • Upgrade from Snow Leopard to Mountain Lion vs. date of computer

    Hello!
    Can somebody tell me if its save to update from Snow Leopard to Mountain Lion if my computer(Macbook) was manufactured in October 2008. Apple recommends that you only do it if your Macbook is from ultimo 2008, but does that include the date before mentioned?
    Secondly, what would happen if I go ahead with the installation and my computer isnt fit to run it?
    Thanks in advance, any help would be much appreciated!

    Mountain Lion can be installed on these MacBook: Late 2008 Aluminum or Early 2009 or newer. You'll need a minimum of 2GB of memory, and 4GB or more is recommended. The late 2008 MacBooks came out in mid-October 2008. You can look at those specs here to ensure your system is this model or key in your serial number here.
    You should have a clone of your system before starting the conversion. If you don't like Mountain Lion, you'll be wiping your disk clean and reinstalling the clone. Most use SuperDuper! or Carbon Copy Cloner to copy the hard drive to another hard drive.
    OS X 10.7 Lion is still available from Apple if you would rather upgrade to it, although you don't need to if you are going directly to Mountain Lion. You call your in-country online Apple store, which in the US is at 800-MY-APPLE, and order Lion. They'll send you a download code to download from the App store.

  • Mail issues when upgrading from Snow Leopard to Lion

    Hello,
    I'm hoping someone out there may be able to answer this question or offer some advice. I am being prompted by Apple to move over to iCloud which requires me upgrading from Snow Leopard to Lion. I am extremely reluctant to do this as I have heard of problems when migrating to Lion, especially with Mail. I presently have over 30,000 emails in my inbox. These mails are divided into a multitude of folders all on my mac. I have a mac email account along with other non Apple email accounts (POP) on my Mac. These emails and the folder structure are fundamental to my work so losing any emails or even the folder structure would be disastrous for me. I have of course made a backup (2 in fact) but do like the idea of trying to rebuild everything from scratch. Any advice would be greatly welcomed. Thanks.

    I'm no expert but at the moment I just woudn't do it as there appears to be lots of unexplained problems with mail and Lion. I have been a Mac user from the earliest days and have never ever had the kinds of problems I am currently having to work around since installing Lion. I wish I had stayed with Snow Leopard.

  • Upgrade from Snow Leopard Server to Lion Server hangs at configuring services...

    I am running the Mac mini with snow leopard server 2.53 ghz 2GB of ram, 2x500GB hard drives, and have followed through the process to install Lion Server. The installation appears to be hung at the Configuring Services section of the setup process. I have left it for a couple of hours and nothing has progressed.
    Should I leave it longer, hoping that it will work through the process (if in fact it is working through something)?
    How long should this normally take?
    As this is my work server, hosting mail, web, FTP, and file sharing, it is rather important to get it up and running as quickly as possible.
    Any thoughts on how I can get it moving?
    Hard power off of the Mac Mini reboots the machine, then proceeds back to the setup page, and then hangs on the same Configuring Services.
    Any assistance would be much appreciated.
    Thanks.

    Lion Server Upgraders,
    beware and proceed with caution.
    Apple web site is naively optimistic on the upgrade process:
    "To upgrade your Mac to OS X Lion, you don’t need to drive to a store, bring home a box, and install a bunch of discs. All you do is click the Mac App Store icon, buy Lion for $29.99, and your Mac does the rest. Just make sure you have what you need to download Lion to your Mac."
    And then has a 3 step process...
    This is completely miss leading.
    Read this document first: http://manuals.info.apple.com/en_US/lion_server_upgrading_migrating.pdf
    It will make it readily apparent that moving from Snow Leopard Server to Lion is not going to be simple.
    Having done this twice now.. I have found that:
    1. Open Directory migration is a weak point. Lion & Snow Leopard Open Directory are not compatible, so if you have masters & replica then expect trouble. I have an unresolved issue trying to get a simple Lion Server to Lion Server Open Directory replica up and running. This compatibility seems to also cause migration to fail, as I found that all my local User/Groups transferred ok but non of the /127.0.0.1/LDAPv3 (Open Directory) ones did. This is a very important item, as all the mail accounts in dovecot use LDAP generated UID, so you have to be careful that you do not loose mail accounts.
    2. Mail - your mail aliases will not transferred, so you will need to reapply the aliases.
    3. Web Server Setup - This broke, under migration as I gather the entire Web serving tree has changed. In particular I had "Snow Leopard" Web Mail (which is based on Squirel) on my "Snow Leopard" Server and this is now dead...
    4. Digital Certificates - I found that the valid (ie signed by trusted CA's) did not get migrated, so I had to re-imported my Digital Certificates. If you have paid for third party CA certificates then make sure you have got these copied somewhere, as if you loose them then you will likely need to go to your provider and get a certificate revocation and new certificate, which will cost you money!
    Cheers,
    Zebity.

  • Upgrade from snow leopard to mountain lion - mac mini

    I would like to upgrade my Mac Mini from snow leopard to maintain lion. The spec says that early 2009 machines are ok but I have bought mine in 2009 and it could have been a 2008 model. Is there a serial number or a utility that I can run to check?
    Thank you

    Check that you computer is compatible with Mountain Lion
    Model Numbers                  Computer Compatibility - Apple 
    Check to make sure your applications are compatible.         Application Compatibility
    If you have applications that you want to use that aren't compatible, you can retain Snow Leopard and create a new partition to install Mountain Lion on.
    If your computer isn't compatible, you might be able to upgrade to Lion.        Computer Compatibility - Lion

  • Upgrade from Snow Leopard to Mountain Lion: Airparrot stopped working

    Hello,
    I used airparrot on my appletv 3 and my <acbook (late 2008) to mirror my screen. However, I updated from Snow Leopard to Mountain Lion and now suddenly, Airparrot cannot find my Appletv anymore, it continues saying: "searching for devices...".
    I already tried rebooting my macbook, disconnecting the electricity of the Appletv unit and removing the Airparrot app. All without result.
    Can someone please help me as this is the only functionality I use my AppleTV for... I want to cry.... I can't even remember why I wanted to upgrade to Mountain Lion except curiosity!
    Any insight is much appreciated.

    I don't use Air Parrot, so you should wait to talk to their tech support to see what they suggest before looking for an issue with OS X. I know nothing about using Airplay, but here's a bunch of help stuff:
    About AirPlay and Airplay Mirroring
    AirPlay Mirroring requires a second-generation Apple TV or later, and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer). For non-qualifying Macs you can try using Air Parrot.
